Open research questions in Genomic variations and chromosomal abnormalities

27 unresolved questions extracted from the limitations and future-work sections of 294 Genomic variations and chromosomal abnormalities papers in our library. Each links back to the study that raised it.

What the literature leaves open

  • While DICER1 mutations are known to predispose individuals to the PPB spectrum, the molecular association between CPAM IV and early-stage PPB remains controversial.

    Case Report: Congenital pulmonary airway malformation associated with a germline DICER1 splicing variant · 2026 · DOI

  • This comprehensive re-analysis highlights the complex structural genomic landscape of POI and suggests that expanding current clinical testing panels to include these under-recognized genes could improve diagnostic yields for genetically unexplained cases.

    Systematic mapping and <i>in silico</i> re-evaluation of genomic copy number variations in Primary Ovarian Insufficiency · 2026 · DOI

  • Future work will focus on stain normalization, upstream instance segmentation to further mitigate borderline overlaps, explicit probability calibration, band-aware representations for acrocentric discrimination, and multi-center validation to assess robustness under heterogeneous imaging conditions.

    Automated karyotyping and structural anomaly detection through a hybrid multi-stage deep learning framework integrating chromosome detection, pairwise classification, and autoencoder-based analysis · 2026 · DOI

  • ” We show that it is possible to infer accurate CNV profiles from DNA meth- ylation microarrays, which is especially beneficial when sam- ple material or resources are scarce, and a dedicated assay for CNV analysis (e.

    Conumee 2.0: enhanced copy-number variation analysis from DNA methylation arrays for humans and mice · 2024 · DOI

  • The performance of a continuous LR model in minor contributor identification in DNA mixtures may not be superior to that of a semi-continuous LR model when the coverage reads of the MPS panel is insufficient.

    DNA mixture analyses of autosomal single nucleotide polymorphisms for individual identification using droplet digital polymerase-chain reaction and massively parallel sequencing in combination with EuroFormix · 2023 · DOI

  • Current research identifies multiple target genes for CIN-exploiting therapeutics (cell cycle checkpoints, sister chromatid cohesion, DNA replication/repair, centrosome duplication, kinetochore-microtubule attachment, chromosome segregation genes), but comparative efficacy studies directly evaluating which gene targets or combinations thereof produce optimal therapeutic outcomes in different cancer contexts are needed.

    Cytogenetics in precision medicine · 2020 · DOI

  • The phenotypic consequences of different BCR-ABL transcript isoforms (P210, P190, P230) and their distinct breakpoints are documented for CML and ALL, but systematic quantification of how these specific isoforms correlate with differential drug response and treatment resistance mechanisms in precision medicine approaches is lacking.

    Cytogenetics in precision medicine · 2020 · DOI

  • The paper identifies that CIN can paradoxically be associated with both poor outcomes in most cancers and favorable outcomes in specific cancer types like CML, but the molecular mechanisms and genetic determinants underlying this differential outcome remain uncharacterized. Future work should systematically compare intratumoral heterogeneity, clonal evolution, and chromosomal aberration patterns between CML and other CIN-positive malignancies.

    Cytogenetics in precision medicine · 2020 · DOI

  • While CIN-reducing and CIN-inducing therapeutic approaches have been successfully demonstrated in vitro using chemical or genetic methods, their translation into clinical applications remains incomplete. Specific clinical trial designs are needed to evaluate the efficacy and safety of these CIN-targeting strategies in primary and metastatic cancer sites.

    Cytogenetics in precision medicine · 2020 · DOI

  • METHODS: We investigated SVs on the male-specific portion of the Y chromosome in the 70 individuals from Africa, Europe, or East Asia sequenced as part of the 1000 Genomes Pilot project, using data from this project and from additional studies on the same samples.

    Structural variation on the human Y chromosome from population-scale resequencing · 2015 · DOI

  • The mechanism of expansion is not well understood, but CGG repeats called intermediate-length or gray zone alleles (approximately equal 35-60 repeats) are thought to make up the FMR1 alleles showing initial steps in this expansion process.

    Haplotype Study of Intermediate-Length Alleles at the Fragile X (FMR1) Gene: ATL1, FMRB, and Microsatellite Haplotypes Differ from Those Found in Common-Size FMR1 Alleles · 2005 · DOI

  • Chromosomal abnormalities are an important cause of congenital 2tmalformation, intellectual disability, disordered sexual development, and infertility, yet population-level cytogenetic data from Libya are scarce.

    Cytogenetic Profile of Patients Referred for Chromosomal Analysis in Eastern Libya: A Five-Year Retrospective Study · 2026 · DOI

  • Such analyses would have provided direct evidence for the pathogenicity of the variants, particularly the missense mutation, and future studies are warranted to address this limitation.
